Understanding childhood obesity
Obesity is a serious medical condition that affects children, adolescents, and adults. Childhood obesity has more than tripled in the United States since the 1970s.
Obese children are above the normal weight for their age and height. To be more specific, a body mass index (BMI) at or above the 95th percentile for children and teens of the same age and sex is considered obese.

Understanding what causes obesity—and the health risks associated with it—helps us find solutions.
